Definitions

  • the present invention relates to a temporary stocking mechanism for temporarily stocking a sheet material by taking up the sheet material on which printing is effected and a printer equipped with the temporary stocking mechanism.
  • a label used while being affixed to a product there is proposed a label issued from a sheet material obtained by providing a printing layer to one surface of a sheet-like base material and a heat-sensitive adhesive layer to the other surface thereof.
  • a printer for effecting printing on the label having the heat-sensitive adhesive layer includes a sheet supply device for supplying the sheet material, a printing device for printing various kinds of information on the printing layer of the sheet material supplied from the sheet supply device, a cutting device for cutting the sheet material on which printing is effected by the printing device, and a thermal activation device for thermally activating the heat-sensitive adhesive layer of the sheet material.
  • a conventional printer including the thermal activation device has a structure in which between the cutting device and the thermal activation device, a guiding device is arranged, for guiding the sheet material while allowing the sheet material to be deformed.
  • a mechanism for temporarily stocking the sheet material, on which printing is effected in the device is a conventional printer including a space for stocking the sheet material on which printing is effected while keeping the sheet material dangling due to a weight thereof.
  • the mechanism for temporarily stocking the sheet material in the related art adopts a method in which the sheet material on which printing is effected is deformed into a U-shape or in a bellows-like fashion, or kept dangling in a predetermined space until a predetermined processing, such as printing or sheet cutting is completed.
  • a structure is devised in which between a printing device and a thermal activation device, there is provided a temporary stocking portion for temporarily stocking the sheet material by taking up the sheet material on which printing is effected and for extracting the taken up sheet materials toward the thermal activation device by drawing out the taken up sheet materials.
  • the temporary stocking portion is provided with a temporary stocking member including a cylindrical take-up space in which the sheet material on which printing is effected by the printing device is taken up.
  • the sheet material on which printing is effected by the printing device rotates, the sheet material is pushed by the transport rollers into the take-up space of the temporary stocking member fixed in position, to thereby be successively taken up from an outer side toward an inner side. At this time, the sheet material on an outermost side to be taken up in the take-up space is pushed by the transport rollers, thereby taking up the sheet material.
  • the sheet material rolled in the take-up space is taken up such that a side of the heat-sensitive adhesive layer faces inwardly in the take-up space.
  • the leading edge of the sheet material is advanced in the take-up space and the sheet material with the leading edge is wound in the take-up space one turn, and then, the leading edge abuts on the heat-sensitive adhesive layer of the sheet material on the outer side. Therefore, the leading edge suffers a relatively large damage due to the heat-sensitive adhesive layer. Accordingly, there is a problem in that an operation of taking up the sheet material stops, so the sheet material is not satisfactorily taken up in the take-up space, therefore a length of the sheet material capable of being taken up in the take-up space is short.
  • the sheet material having a width of about 30 mm to 50 mm when advanced into the cylindrical take-up space having an inner diameter of about 25 mm, the sheet material is wound in the take-up space about one turn, so it is only possible to take up the sheet material having a length of about 100 mm.
  • a spiral-shape guide portion for guiding the sheet material is molded out of a resin material to be integral with the temporary stocking member.
  • a radius of curvature of the guide portion is smaller than a radius of curvature of an inner peripheral surface of the temporary stocking member, so a transportation load of the sheet material increases. Therefore, by molding the guide portion integrally with the temporary stocking member, there is a disadvantage in that a length of the sheet material to be taken up, that is, an amount of the sheet material which can be taken up is reduced.
  • JP 2000-044100 discloses a printer in which a paper transport direction may be reversed by rolling the paper around a reversing roller.
  • JP 2001-130828 discloses a printer in which paper may be wound around a take up roller in conjunction with a press contact roller.
  • the press contact roller may be moved out of a working position.
  • the temporary stocking mechanism includes: a temporary stocking member having a cylindrical take-up space in which a sheet material is taken up, for temporarily stocking the sheet material on which printing is effected by a printing means; a take-up roller provided in the take-up space, for taking up the sheet material; a driving means for rotationally driving the take-up roller; and a press-contact means for bringing a peripheral surface of the take-up roller into press contact with an inner peripheral surface of the temporary stocking member.
  • the sheet material advanced into the take-up space of the temporary stocking member advances along the inner peripheral surface of the temporary stocking member to be sandwiched between the inner peripheral surface of the temporary stocking member and the peripheral surface of the take-up roller.
  • the sheet material sandwiched between the temporary stocking member and the take-up roller is advanced in a satisfactory manner as the take-up roller is rotationally driven by the driving means.
  • the sheet material is then smoothly taken up along the inner peripheral surface of the temporary stocking member.
  • the temporary stocking member of the temporary stocking mechanism according to the present invention is composed of a plurality of members which are combined with one another so as to be capable of being separated so that the take-up roller is exposed to the outside.
  • a printer includes : the temporary stockingmechanismaccording to the present invention; and a printing means for effecting printing on the sheet material.
  • a sheet material used for the label issuing device of this embodiment includes a sheet-like base material, a heat-sensitive printing layer provided on a front surface side of the sheet-like base material, and a heat-sensitive adhesive layer provided on a rear surface side of the sheet-like base material.
  • the sheet material may adopt a structure in which, between the sheet-like base material and the heat-sensitive printing layer, a heat insulating barrier is provided, for blocking heat transfer from the layer on one side of the sheet-like base material to the layer on the other side thereof.
  • a label issuing device 1 includes a sheet supply portion 11 for supplying a sheet material 5 along a transport direction of the sheet material 5 indicated by arrows L of FIG. 1 , a printing portion 12 for printing various kinds of information in a form of characters or the like on a heat-sensitive printing layer of the sheet material 5, a cutting portion 13 for cutting the sheet material 5 on which printing is effected by the printing portion 12 into a predetermined length, a temporary stocking portion 14 for temporarily stocking the sheet material 5 on which printing is effected by the printing portion 12, a thermal activation portion 15 for thermally activating a heat-sensitive adhesive layer of the sheet material 5 supplied from the temporary stocking portion 14, and a pair of discharge rollers 16a and 16b for discharging the sheet material 5 to the outside the device.
  • the sheet supply portion 11 is provided with a supply roll 11a obtained by winding the sheet material 5 into a roll, in a rotatable manner.
  • the sheet material 5 is supplied by being delivered from the supply roll 11a having an outer diameter of about 50 mm.
  • the printing portion 12 is a so-called thermal printer and includes a thermal head 12a for allowing the heat-sensitive printing layer of the sheet material 5 to sense heat, and a platen roller 12b brought into pressure contact with the thermal head 12a.
  • the sheet material 5 supplied from the sheet supply portion 11 is sandwiched between the thermal head 12a and the platen roller 12b and is subjected to printing while being transported.
  • the cutting portion 13 includes a cutter 13a for cutting the sheet material 5 transported from the printing portion 12 into a predetermined length and a cutter displacement mechanism (not shown) for moving the cutter 13a.

  • the temporary stocking member 21 is formed, for example, of a resin material and includes a cylindrical take-up space 21a into which the sheet material 5 transported by the transport rollers 18a and 18b is taken up. In a position adjacent to the transport rollers 18a and 18b, the temporary stocking member 21 is provided with a sheet passage 21b continuous with the take-up space 21a. Note that, the take-up space 21a is formed to have an inner diameter of about 25 mm and a width larger than a width of the sheet material 5.
  • the take-up space 21a is formed to be larger in width than the sheet material 5. Therefore, even in a case where a take-up position of the sheet material 5, which is wound to form the supply roll 11a, is moved in a width direction, that is, a so-called wind displacement in the width direction occurs, side edges of the sheet material 5 in the width direction is prevented from abutting on side walls in the width direction of the take-up space 21a, so the sheet material 5 can smoothly be taken up.
  • the temporary stocking member 21 is movably supported so as to be close to and spaced apart from the take-up roller 22. With a pressure applied from the coil spring 27, the temporary stocking member 21 is biased such that an inner peripheral surface thereof comes into contact with a peripheral surface of the take-up roller 22.

  • the take-up roller 22 is supported by a rotation shaft 22a and can be allowed to rotate by a rotationally driving mechanism 28 through an intermediation of the rotation shaft 22a in a normal direction and a reverse direction. Further, the rotationally driving mechanism 28 allows the take-up roller 22 to rotationally drive in accordance with rotational speeds and rotation directions of the transport rollers 18a and 18b.
  • the take-up roller 22 is arranged in a position substantially opposed to a position of an in/out opening of the sheet passage 21b of the temporary stocking member 21 with respect to a center of the take-up space 21a so as to abut on the inner peripheral surface of the temporary stocking member 21. That is, the sheet material 5 introduced into the take-up space 21a is sandwiched between the peripheral surface of the take-up roller 22 and the inner peripheral surface of the temporary stocking member 21 at a position where the sheet material 5 reaches after being advanced about halfway along the inner peripheral surface of the temporary stocking member 21, and the take-up roller 22 is rotated, thereby allowing the sheet material 5 to be advanced and smoothly taken up along the inner peripheral surface of the temporary stocking member 21.
  • the take-up roller 22 is formed to have a width of about 54 mm, which is a little larger than the maximum width of the sheet material 5 to be used, and an outer diameter of about 17 mm.

  • the sheet material 5 sandwiched between the take-up roller 22 and the driven roller 35 is advanced in a satisfactory manner as the take-up roller 22 and the driven roller 35 rotate.
  • the leading edge of the sheet material 5 further advances along the inner peripheral surface of the sheet material 5 which is wound along the outer peripheral side of the take-up space 21a. Accordingly, the sheet material 5 is smoothly taken up along the inner peripheral surface of the temporary stocking member 21.
  • the sheet material 5 having the width of about 28 mm to 52 mm is taken up in the temporary stocking member 21, so the sheet material 5 is smoothlywound in the take-up space 21a about four turns. Accordingly, the sheet material 5 having the length of about 350 mm is taken up in a satisfactory manner.
  • the sheet material 5 is cut by the cutting portion 13 and the sheet material 5 of the desired length is stocked, and then, the pair of transport rollers 18a and 18b, the take-up roller 22, and the driven roller 35 of the temporary stocking portion 34 are driven in reverse directions, respectively, in synchronism with one another. As a result, the sheet material 5 is transported from the temporary stocking portion 34 to the thermal activation portion 15.
  • the temporary stocking portion 34 having the driven roller 35 to be brought into press contact with the take-up roller 22 for taking up the sheet material 5, thereby allowing the sheet material 5 to be sandwiched between the take-up roller 22 and the driven roller 35, so it is possible to further improve reliability of the operation of taking up the sheet material 5.
  • the sheet material 5 is taken up in the take up space 21a more smoothly, thereby increasing the length of the sheet material 5 to be taken up in the temporary stocking member 21.
  • the temporary stocking member 21 described above be structured in a manner in which the take-up roller 22 in the take-up space 21a can be exposed to the outside.
  • the temporary stocking member 21 may be structured so as to be capable of being divided into an upper component and a lower component as shown by a broken line D of Fig. 3 .
  • the take-up roller 22 is exposed to the outside, thereby making it possible to quickly solve the problem. As a result, it is possible to improve workability in maintenance of the temporary stocking portion.
  • the sheet material 5 having the heat-sensitive printing layer is described as one example.
  • the present invention may be applied, for example, to a purpose of temporarily stocking the sheet material on which printing is effected by allowing ink droplets to adhere onto the printing layer thereof to be absorbed therein by using an ink jet recording method.
  • the printer is not limited to the structure employing the sheet material having the heat-sensitive layer, the printer may have a structure in which the sheet material on which printing is effected is temporarily stocked, and then, is discharged from the temporary stocking portion.
